Genera and Species of Phytophaga. (231 
Clitena melancholica. 
Subelongata, convexa, nigra, subopaca; thorace rugoso, irregu- 
lariter excavato, elytris crebre punctatis, pube brevi adpressa 
concolori dense vestitis. 
Long. 51 lines, 
Hab. Laos, Siam. 
Head coarsely punctured, excavated on the front; antenne more 
than two-thirds the length of the body, sixth and following joints 
compressed and dilated, ninth, tenth and eleventh very short, 
decreasing in width. Thorax scarcely twice as broad as long, 
sides rounded at the base, nearly straight and subparallel along 
their middle, thence quickly narrowed to the apex, anterior angles 
thickened; surface irregular and excavated. Elytra subparallel 
in front, scarcely dilated posteriorly, much more finely punctured 
than the thorax. 
Genus Lapuris. 
Corpus oblongo-elongatum, convexum. Caput exsertum, facie 
perpendiculari; antennis modice robustis, filiformibus, arti- 
culo secundo brevissimo; palporum articulis duobus ultimis 
conjunctim ovatis. Jhorax transversus, dorso utrinque trans- 
versim sulcatus. Llytra oblonga, irregulariter punctata. 
Pedes modice robusti; coxis anticis fere contigws, perpen- 
dicularibus, femoribus posticis non incrassatis ; tibiis posticis 
apice spina brevi armatis, waguiculis appendiculatis. Meta- 
sternum antrorsum ultra coxas intermedias productum. 
Type Laphris emarginata. 
Nearly allied to Aplosonyx, separated by the appendiculated 
claws and produced metasternum. 
. 
Laphris emarginata. 
Oblongo-elongata, parallela, convexa, pallide fulva, nitida; oculis 
elytrorumque vitta lata, mox infra basin fere ad apicem 
extensa, extus sat profunde emarginata, nigris; antennis 
(basi excepta) fuscis. 
Long. 5 lin. 
Hab. Northern China. 
Thorax nearly twice as broad as long, coarsely punctured, 
impressed in the middle of the base with a large fovea; sides
